Gulu
Kukweza ndi kulumikiza, kukweza unyolo,unyolo waufupi wolumikizira, kukweza unyolo wozungulira wolumikizira,Unyolo wa Giredi T, unyolo wa Giredi DAT,Unyolo wa DT wa Giredi, DIN EN 818-7unyolo waufupi wolumikizira zinthu zonyamulira,unyolo wonyamulira wololera bwino,unyolo wachitsulo cha aloyi
Kugwiritsa ntchito
Kukweza ndi kulumikiza, kukweza katundu, kumanga katundu
Monga wopanga unyolo wozungulira wa zitsulo kwa zaka 30, fakitale yathu yakhala ikugwira ntchito ndi kutumikira nthawi yofunika kwambiri ya kusintha kwa makampani opanga unyolo ku China popereka chithandizo cha migodi (makamaka mgodi wa malasha), kunyamula zinthu zolemera, ndi kunyamula katundu m'mafakitale pa unyolo wozungulira wa zitsulo wamphamvu kwambiri. Sitimayima pa kukhala opanga unyolo wozungulira wozungulira ku China (wokhala ndi matani opitilira 10,000 pachaka), koma timapitiriza kupanga zinthu zatsopano mosalekeza.
